Map the installed footprint
Measure rooms, closets, alcoves, and connected passages that receive the plank.
Keep different colors, formats, or installation directions as separate order lines.
Model cut loss
Straight rectangular layouts often reuse more offcuts than diagonal or broken layouts.
Transitions, doorways, islands, and direction changes can increase non-reusable pieces.
Use the carton label
Product carton coverage is the procurement basis and can vary even among visually similar planks.
Verify the exact SKU before ordering.
Round to full boxes
Adjusted area divided by carton coverage gives theoretical boxes; round up to the next whole package.
Add intentional attic stock only after installation quantity is established.
Verify system details
Expansion, substrate preparation, moisture, attached pad, underlayment, adhesive, and perimeter details are product-specific.
Follow the selected manufacturer's installation guide.
